Timers’ functions for three-phase motor control
Timers’ functions for three-phase motor control
Figure 1.15.1. Registers related to timers for three-phase motor control
Use of more than one built-in timer A and timer B provides the means of outputting three-phase motor
driving waveforms.
Figures 1.15.1 to 1.15.3 show registers related to timers for three-phase motor control.

hree-phase PWM control register 1
No value other than “0” can be written.
Selecting three-phase PWM output mode causes P8
timer for setting short circuit prevention time, the U, V, W phase output control circuits, and the circuit for setting timer B2 interrupt
frequency.
In triangular wave modulation mode:
The short circuit prevention timer starts in synchronization with the falling edge of timer Ai output.
The data transfer from the three-phase buffer register to the three-phase output shift register is made only once in synchronization
with the transfer trigger signal after writing to the three-phase output buffer register.
In sawtooth wave modulation mode:
The short circuit prevention timer starts in synchronization with the falling edge of timer A output and with the transfer trigger signal.
The data transfer from the three-phase output buffer register to the three-phase output shift register is made with respect to every
transfer trigger.
To write “1” to bit 1 (INV01) of the three-phase PWM control register 0, set in advance the content of the timer B2 interrupt
occurrences frequency set counter.

Note : To use three-phase PWM output mode, write “1” to INV12.
Noting is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns out to be “0”.
